INSULATION WITH STRUCTURAL PERFORMANCE

Precision Stock Shapes for Electrical Components.

Electrical and electronic assemblies often need components that combine dielectric separation with mechanical strength, dimensional stability, heat resistance and accurate machining.

Engineering plastics can be evaluated for insulators, terminal supports, coil formers, spacers, arc barriers, test fixtures and structural parts across power distribution, automation and electronic equipment.

ZERO supplies semi-finished rods and sheets for further machining. Electrical ratings, flame classifications and compliance depend on the exact material grade, thickness, test method and operating conditions.

ELECTRICAL PERFORMANCE REQUIREMENTS

Properties to Verify for the Exact Component.

Required values depend on voltage, frequency, part thickness, temperature, humidity, contamination level and applicable standards.

ELECTRICAL APPLICATION FAQ

Before Selecting an Electrical Insulation Material.

These answers are general. Use the exact grade datasheet and applicable equipment standard for final validation.

PEEK, PPS, PEI, PTFE, POM and other grades can provide electrical insulation in different conditions. The correct choice depends on voltage, frequency, temperature, humidity, geometry, mechanical load and required approvals.

No. Test method, specimen thickness, conditioning, temperature and exact formulation affect the reported value. Use grade-specific data under conditions relevant to the component.

No. Flame ratings are specific to the exact grade and tested thickness. Color, reinforcement and other formulation changes may also matter. Verify current supplier documentation.

Consider continuous and peak temperature, heat aging, dielectric behavior, thermal expansion, mechanical stress, creepage, clearance and possible exposure to oils, coolants or cleaning chemicals.

Please provide the drawing, voltage and frequency, operating temperature, environment, mechanical load, required electrical or flame classification, stock dimensions, tolerance and quantity.
